Geodes are a type of natural rock formation that contains a cavity lined with crystals or other types of mineral. The hollow pocket inside is formed by volcanic forces or chemical precipitation. Water gets into a rock through fine cracks, and as the water evaporates, the minerals and other impurities left behind form the crystals. The word Geode comes from the Greek term, Geoides, which means Earth-like.
Geode banding and coloration is the result of different impurities during formation. Most geodes contain clear quartz crystals, while others have amethyst crystals that can come in a range of colors. Some geodes can have agate, chalcedony, or jasper banding, along with crystals such as calcite, celestite, etc. There is no easy way of telling what the inside of a geode holds until it is cut open or broken apart!
Geode can be used for home decor and jewelry. Larger specimens can be faceted into bookends and countertops for tables.
Geodes can help in communicating with divine beings. It balances and improves moods and provides energy for meditation, reduces stress, and aids decision-making. Geodes are often viewed as a feminine property due to the cavity which resembles the womb.
